1782R-53F

Fixed Inductors Overview

The Delevan 1782R-53F is a fixed, unshielded molded axial leaded inductor designed for RF applications. It features a nominal inductance of 24 µH with a tight tolerance of ±1%. The component supports a maximum DC current of 135 mA and has a maximum DC resistance of 3.5 Ohms. It operates within a temperature range of -55°C to 105°C and utilizes a ferrite core material.

Fixed Inductors Feature Summary

• Unshielded molded construction for compact integration
• Axial through-hole termination style
• Ferrite core design optimized for RF frequencies

Fixed Inductors Applications

• RF circuit filtering
• Impedance matching networks
• General purpose RF signal processing

Fixed Inductors Procurement Notes

Verify the specific suffix 'R' against official manufacturer documentation to confirm tape-and-reel packaging status, as standard series parts may vary in delivery format. Ensure the ferrite core specification aligns with target frequency requirements. Confirm RoHS compliance status directly with the supplier, as historical data indicates potential variations within the 1782 family.

Fixed Inductors Selection Notes

Select this component when a 24 µH inductance with high precision (±1%) is required for axial mounting. The 135 mA current rating suits low-power RF stages. Consider the unshielded nature for layout planning to minimize crosstalk in dense PCB designs compared to shielded alternatives.

Fixed Inductors Part Context

This part belongs to the Delevan 1782 series of RF inductors. The series offers various inductance values with tight tolerances, utilizing molded epoxy encapsulation over ferrite cores. These components are engineered for stability in radio frequency environments, providing consistent performance across wide temperature ranges.

Fixed Inductors Replacement Considerations

Direct substitutes within the same series include other 1782 variants with compatible inductance and tolerance. Verify physical dimensions and lead spacing before substitution to ensure board compatibility.
